GDad: So you have no capacity to make intelligent decisions on your own? If that's the case, I expect you to stop trying to make any decisions, and I will tell you what to do and when to do it for the rest of your life. Does that sound like a fun time?

GDad: Just because you can do something doesn't mean you should. And just because you're allowed to do something doesn't mean it's a good idea. Now go read that book.
